structures of ecoysystems |
| Answer» Ecosystem is defined as the structural, functional and self-sustaining unit of biosphere, which consists of biotic and abiotic components.Biotic components of ecosystem: Producers are the green plants which can prepare food themselves. Green plants can prepare their own food due to the presence of chlorophyll. For e.g.: Sunflower, mango plant.Consumers are the heterotrophs that depend on green plants directly or indirectly for their food. For e.g.: Dog, Lion etc.Decomposers are the saprophytic organisms that feed on dead and decaying organic matters and decompose them into simpler forms. For eg: Bacteria, Fungi etcAbiotic components are the non-living chemical and physical factors in the environment that affect ecosystems. Abiotic components play a crucial role in all of biology. Abiotic factors are broadly grouped into physiographic, edaphic and climactic factors and atmospheric gases. | |
